Mutatably transparent displays

1. A method for controlling a computer, the computer having a display and operating at least one application program responsive to a user-controlled pointer and responsive to actuation of at least one control selected from at least one set of controls, wherein at least one control has at least two modes of display wherein each mode includes a set of display characteristics, and each control has boundaries and a position, the method comprising: executing the application program; displaying one or more sets of controls as a function of the application program; comparing the position of the pointer with the position of at least one control; determining the state of at least one application program; and selecting the mode of at least one set of controls, wherein selecting the mode includes adjusting the opacity of a control.

2. A method for controlling a computer, the computer having a display and operating at least one application program responsive to a user-controlled pointer and responsive to actuation of at least one control selected from at least one set of controls, wherein at least one control has at least two modes of display wherein each mode includes a set of display characteristics, and each control has boundaries and a position, the method comprising: executing the application program; displaying one or more sets of controls as a function of the application program; comparing the position of the pointer with the position of at least one control; determining the state of at least one application program; and selecting the mode of at least one set of controls, wherein selecting the mode includes adjusting the opacity of a set of controls.

3. A method for controlling a computer, the computer having a display and operating at least one application program responsive to a user-controlled pointer and responsive to actuation of at least one control selected from at least one set of controls, wherein at least one control has at least two modes of display wherein each mode includes a set of display characteristics, and each control has boundaries and a position, the method comprising: executing the application program; displaying one or more sets of controls as a function of the application program; comparing the position of the pointer with the position of at least one control; determining the state of at least one application program; and selecting the mode of at least one set of controls, wherein selecting the mode of at least one set of controls includes adjusting the mode of display of the controls that are operative.

4. A method for controlling a computer, the computer having a display and operating at least one application program responsive to a user-controlled pointer and responsive to actuation of at least one control selected from at least one set of controls, wherein at least one control has at least two modes of display wherein each mode includes a set of display characteristics, and each control has boundaries and a position, the method comprising; executing the application program; displaying one or more sets of controls as a function of the application program; comparing the position of the pointer with the position of at least one control; determining the state of at least one application program; selecting the mode of at least one set of controls; and increasing the level of opacity of a set of controls as the pointer approaches a selected control.

5. A computer-readable medium for a computer having an executable program stored thereon comprising: means for causing the computer to perform a particular function; means for providing one or more controls for use with the executable program and displayable within a graphical user interface, each of the one or more controls have a position and boundaries and are user-accessible and operable by a user-controlled and re-positionable pointer, the one or more controls having a first display configuration wherein at least one of the controls has a first predetermined level of opacity, and a second display configuration wherein at least one of the controls has a second predetermined level of opacity, wherein the first predetermined level of opacity is different from the second predetermined level of opacity, such that occurrence of a particular event changes the display configuration of the one or more controls, and wherein the level of opacity of at least one of the controls is a function of the position of the pointer relative to a selected control.

6. The computer-readable medium of claim 5, wherein the particular event comprises positioning of the pointer within the boundaries of a selected control.

7. The computer-readable medium of claim 5, wherein the particular event comprises a predetermined state of execution of the executable program and particular positioning of the pointer relative to the position of a selected control.

8. The computer-readable medium of claim 5, wherein the medium is a floppy disk.

9. The computer-readable medium of claim 5, wherein the particular function of the application program comprises a virtual appliance mimicking a device external to the computer on which the executable program is running.
